To get back on track and respond to the OP: I'd agree with the general thrust of the post. While evidence-based medicine has improved the state of medical interventions somewhat, there are certain areas of medical practice where expert opinion reigns supreme and ex cathedra pronouncements form the majority of discourse, e.g. psychiatry.
These attempts to ''restore balance'' are little more than interventions to produce a simulation of health, i.e. the person appears ''better'' or more normal, but his ''normality'' is not of ''genuine'' origin.
How this is to be rectified, I am unsure. Certainly, these professions are slow to change, given their privileged social position, the many unknowns about the human body and the risk to people's lives. Perhaps studies investigating the relative merits of drug therapy versus psychological interventions.
Some situations, such as ADHD, may not require psychiatry or psychology.. here, we might ask, is the environment perhaps at fault? As in, there is not some, simple ''mechanical'' problem with the child, but that the environment in which they are embedded is wholly at odds with their nature.
As you suggest Dave, the best (and perhaps only!) thing the individual can do is run the hell away from any psychiatrist!
